clutch cable gaiter oil leak

[davy-b]

Hi
2000 883 sportster, low mileage.
Working back in the UK so using bike for commuting 6 mile trips.
Noticed oil coming from the rubber gaiter in the cable, not much, but first time I have seen this.
Working on the possibility of primary case breather blocked and pressure build up has forced oil up the cable.
I believe there was a workshop instruction from HD about rerouting the breather, has anybody got a copy they could send me or any other ideas about what could have caused it.
